A Secure Virtual Point of Service (SVPOS) that coordinates the authentication, authorization, and identity, settlement, arbitration and non-repudiation for an electronic commercial transaction. For each commercial transaction, both the buyer and merchant authenticate itself to the SVPOS and create two unique transaction encryption keys, one for the buyer and one for the merchant. The merchant uses both encryption keys to encrypt a package that include at least product identification. The merchant and buyer calculate a hash of the package and transmit the calculated hash to the SVPOS for comparison to prevent repudiation. If the calculated hash is identical the buyer receives the merchants encryption key and decrypts the package. Payment is released by the SVPOS if the buyer is satisfied with the package via a Parlay system. If the buyer is not satisfied, said SVPOS performs arbitration between the buyer and merchant to determine if the package is correct.

Method and apparatus to conduct a commercial transaction over wireless networks

In a telecommunications network in which a mobile handset is capable of communicating in both an IP domain and a non-IP domain, the handoff of an existing communications session between the mobile handset and a fixed user is facilitated by a handoff controller implemented in a service control point. The handoff controller implements different handoff methods depending on the status of the fixed user and the transition of the mobile user. Additionally 802.21 Media Independent Handover Function in conjunction with SIP is used to facilitate handover between IP and Non-IP points in the system.
